KacMoody groups can be seen as infinitedimensional generalisations of Chevalley groups. However, our approach will use integration of the adjoint representation of the associated KacMoody Lie algebra and a functorial definition due to J. Tits. Unitary forms arise as the fixed point subgroup with respect to a 'twisted' Chevalley involution on the KacMoody groups.
